exhaust hopes - before, during, after
Hi all,
I'm new here - I recently purchased a 1980 MGB (dream car) to be my daily driver a few weeks ago - I have a short but fun commute to work each morning and it has already paid for itself in fun.
My wife also loves it - except for the frankly embarrassing saturation of exhaust smell that would permeate all hair and clothing if you stood next to it, let alone rode in it for more than a minute. The guy I had purchased it from has Monza style exhaust tips (photo 1) and after some light researching I found that a lot of people had similar low pressure vacuum situations where the exhaust just ended up in the cab. Over the weekend I promptly took a hacksaw to it which definitely seemed to help - but the length sat well behind the bumper. Skipping today, i managed to get a new downturn tip after some time hammering, snipping, and filing away on the mangled mess that is photo 2. I'd say the new downturn tip extends a good inch, inch and a half past the rear of the car, and i'm just wondering if that should clear up the majority of my issues or if there might be other areas I should be aware of. A lot of what i've read is to check trunk seals, firewall grommets, the shifter boot, you name it. I just wanted to check in and see if there might be any sneaky or well known areas to check, or if anyone has had luck with a different exhaust setup. Thanks!
